The modern Australia, the Australia of the 21st Century, Malcolm Turnbull's Australia has nothing to do with the kind of protectionist and xenophobic attitudes that Pauline Hanson represents.

A dining club which I was involved in at Oxford University invited Sir Isaiah Berlin to dinner, who I believe was probably the greatest liberal philosopher in the 20th century. I sat beside him and we spoke about liberal philosophy and the events of the 20th century all night over dinner - it was unforgettable!

Let's be frank: if there are hardened terrorists [Australian] who are fighting overseas, we don't want to see those people come back to our shores. But if we could stop youngsters, teenagers from falling into the snares of ISIL or Jabhat al-Nusra or other terrorist organisations through parental intervention and other strategies then, we hope to be able to rescue them before they commit these crimes.

I am because the Chinese have agreed - entered into this agreement in 1997. It sets out the circumstances in which the release of a prisoner who is the subject of a transfer may occur in exceptional circumstances. So the Chinese, having agreed to those principles, I'm sure have no objection to them being applied in this particular case.

I'd say about Malcolm Fraser, as he said about himself, is that he was always, from the day he entered Parliament in 1955 until the day he died today, was a Liberal.

The political bug first bit me was Malcolm Fraser's resignation from the Gorton Government.

Malcolm Fraser, in the marrow of his bones, despised racism. He despised people who discriminated against other people because they were different and in particular because of the colour of their skin, and I don't think there has been a time in Australian politics where there has been more attention to the importance of that value.
